Introducción. Escherichia coli secuenciotipo 131 (ST131) es un clon que combina capacidad de propagación exitosa, resistencia a los antibióticos y virulencia; de hecho, los aislamientos de ST131 generalmente exhiben los factores de virulencia asociados característicos de las cepas de E. coli patógenas extraintestinales (ExPEC). Este clon se ha...

Background Escherichia coli sequence type 131 (ST131) is a successful clonal group that has dramatically spread during the last decades and is considered an important driver for the rapid increase of quinolone resistance in E. coli. Methods Risk factors for rectal colonization by ST131 Escherichia coli (irrespective of ESBL production) were...

The epidemiology and outcomes of bloodstream infections (BSIs) caused by Escherichia coli ST131 isolates not producing extended-spectrum β-lactamases (ESBLs) are not well defined despite being more prevalent than ESBL-producers. In this study, risk factors and the impact on outcome of BSIs caused by non-ESBL-producing ST131 E. coli versus...
